Cannot sign into console companion "system cannot find the file specified"

Try uninstalling and reinstalling the app. Also, make sure your PC is fully updated.

I fixed the issue on my own. On this day i found out in xbox gamebar that i cannot log in there on social tab. It showed that they cannot sign me into xbox live (The system cannot find the file specified) so i fixed thanks to JeffreyCloutier in this dicussion https://answers.microsoft.com/en-us/windows/forum/all/the-system-cannot-find-the-file-specified-xboxbeta/b7d0ae26-f24f-460e-954e-65fa61641d0d

Hi. My name is Brilliant, an independent advisor, happy to assist today.

Seeing that you have tried multiple troubleshoots without any solution, I advise you consider resetting your Windows. Resetting your PC lets you perform a clean reinstallation and update of Windows while keeping your personal data and most Windows settings intact. In some cases, a clean installation may improve your device's performance, security, browsing experience, and battery life.

However, I'll still share the basic troubleshooting tips in case you can find something that you may have not yet tried.
- Restart your device.
- Update Windows.
- Update your device drivers.
- Update the Xbox and Gaming Services apps.
- Sign into the Xbox app and Store using the same account.
- Remove and reinstall Gaming Services.
- Make sure your date and time is correct.
- Disable your antivirus.
- Use the app troubleshooter.
- Repair and reset the Xbox app.
